The spraying tooling includes an assembly line, multiple wheel hub bases each capable of moving on the assembly line, multiple driving mechanisms each capable of driving a wheel hub base to rotate at a preset position on the assembly line, multiple triggering components each capable of triggering a driving mechanism to operate, multiple maintaining components each capable of maintaining a preset time for a triggering component, and a control component; the wheel hub base includes a sliding seat capable of moving on the assembly line and a tray capable of rotating along with rotation of the driving mechanism, and the tray is rotatably mounted on the sliding seat; and all of the driving mechanisms and the triggering components are electrically connected to the control component.

A coating apparatus includes a process chamber, a rotation device, and a rotation holder. The rotation device is disposed in the process chamber. The rotation holder is connected to the rotation device. The rotation holder includes two extension elements, two retaining elements, and two pins. The two extension elements are disposed around a center axis and separated from each other, wherein each of the two extension elements has a side surface. Each of the two retaining elements has a bottom surface, one of the two retaining elements is connected to one of the side surfaces, and the other of the two retaining elements is connected to the other of the side surfaces. One of the two pins is connected to one of the bottom surfaces, and the other of the two pins is connected to the other of the bottom surfaces.

Systems and methods are provided for securement of parts. One embodiment is a method for securing a part during fabrication. The method includes forming an interference fit between a pin and a wall defining a hole, supporting a weight of the part with the interference fit, and rotating the part around an axis of the part while the weight of the part is supported.

This invention discloses a mechanical boost type cup spray-washing unit integrated with temperature-adjustment and press-control. This unit may regulate the mixing proportion of the cold water and hot water. It in combination with the boosting spray-wash effectively dissolves and washes the residues and juice on the inner wall of cup. This unit is clever in structure, integrates the temperature-adjustment and flush-washing, is directly hidden in the intermediate of the desk installation holes, never occupies surplus space of the kitchen desk, and may be installed in the standard small-hole of the kitchen water-trough desk without extra-opening, or may be directly fixed above the bottom of the water-trough after removal of the drain-panel.

Disclosed is a protective paint spraying equipment for a wheel hub including a centering device, a paint spraying device and a review device. This equipment covers a protective paint film with a certain hardness and transparency on a QR code of the hub, effectively avoiding damage to the QR code by the hub during the loading process, ensuring full flow traceability of the hub.

A spherical core spraying tool comprises a spraying spindle and connecting rods; the spraying spindle is circumferentially provided with a plurality of protruding rings, and is axially provided with a strip-shaped groove; the connecting rods are disposed in the groove; one end of the spraying spindle is a power input end, and the other end is provided with a locking sleeve; the groove runs through the protruding rings. By spot-welding steel balls in an inner hole of a spherical core and fitting the spherical core over the spraying spindle, the steel balls are stuck in the groove of the spraying spindle, and the both sides of the steel balls are tightened by means of the connecting rods in abutting-against fashion, so that a plurality of spherical cores is fixed together with the spraying spindle, and the plurality of spherical cores can be spray-coated simultaneously, thereby improving the efficiency.

The method includes forming an interference fit between a pin and a wall defining a hole, supporting a weight of the part with the interference fit, and rotating the part around an axis of the part while the weight of the part is supported.

Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.

A stand for receiving an object, e.g., an automobile panel, may include a base support configured to engage a ground surface, an upright support extending upward from the base support, and one or more object coupling apparatus. For example, the object coupling apparatus may include an upper support element coupled to the upright support that provides an elongate support element elevated above the ground surface and one or more various arms movable along the elongate support element that couple to the object.

An airframe handling apparatus is operable to support and move a partially assembled aircraft fuselage. The aircraft fuselage is incomplete, lacking a wing and landing gear. The apparatus is attachable to the aircraft fuselage in place of the wing and landing gear, utilizing wing attachment structures on the aircraft fuselage that are designed for flight loads. With the aircraft fuselage attached to the apparatus, the entire fuselage is supported on the apparatus that can be operated to move and manipulate the aircraft fuselage as if the wing and landing gear were present. With the apparatus attached to the aircraft fuselage, movement of the fuselage by the apparatus imparts no handling-induced internal loads on the aircraft fuselage, and maximizes unobstructed access to the exterior surface of the fuselage for painting and other surface preparations.
